The Honeywell MN Series portable air conditioner has a sleek, modern design cooling and dehumidifying areas 300-450 square feet. With 3-in-1 technology, this portable air conditioner delivers optimum cooling and dehumidification. It also has a fan-only function. The full-function remote control allows you to operate each feature from across the room. Unlike a fixed AC, this unit requires no permanent installation and four caster wheels provide easy mobility between areas. Plus, the auto-evaporation system allows for hours of continuous operation with no water to drain or no bucket to empty. This MN10CESWW comes with everything needed including a flexible exhaust hose and an easy-to-install window venting kit. The window vent can be removed when the unit is not in use.
